The name alone conjures images of Arabian Knights and rose-scented gardens, but the reality is even more colourful. Barry roams around one of the most exciting market squares on the planet, with families of acrobats, snake charmers and dream merchants all vying for attention. And as the sun goes down he watches it transform into the biggest outdoor café in the world. It's where the locals tuck into delicacies like sheep's head, while the tourists stick to sausages and chips. Why are all the ceilings so intricately decorated? And what makes the baker the man to know in the neighbourhood? And how would you use a hammer to make a cup of tea? Marrakech has got to be the greatest show on earth.
